2. Disassembly 



2,1 Group Disassembly- Disassembly of the 
H&K Pistol P7M13 into its three principal 
groups Is al! that is required foe normal main- 
tenance. Those weapons purchased directly 
from Heckler and Koch, Incorporated (HK, 
IncJ have a five<year limited warranty, and 
I heir barrels are guaranteed to fire up to 
10 F 000 rounds. If malfunctions covered by the 
warranty occur, the weapon will be replaced 
or repaired by HK, Inc. After expiration of the 
warranty, damaged weapons will be refur- 
bished by HK, Inc. at a nominal cost. Never- 
theless, when and wherever further disas- 
sembly of H&K Pistol P7M13 is required, 
these operations may be accomplished as 
follows: 

2.1.1 Clear the Piece. Hold the H&K Pistol 
P7M13 with the right hand (Figure 4) and pull 



the slide (Part 1, Figure 2) to the rear with the 
left hand. As the slide is pulled to the rear and 
locked In its rearmost position, look into the 
chamber and ensure that it is empty. 

2.1,2 Magazine Assembly Group, After ensur- 
ing that the piece is clear of rounds, the 
magazine assembly group (Part 3, Figure 2) Is 
removed from the H&K Pistol P7M13. This is 
accomplished by depressing the magazine 
catch (Part 50, Figure 3) with the thumb of 
either hand and catching the released maga- 
zine with the other hand {Figure 5). 

2.T.3 Disassembly of Slide Assembly Group 
From Barrel end Receiver Group- To dis- 
assemble the slide assembly group from the 
barrel and receiver group, let the slide snap 
forward by squeezing the cocking grip (Part 
38, Figure 3). When the slide is in its forward 
position, press the disassembly button (Part 
32, Figure 3) and pull the slide to the rear as 
shown in Figure 4. As the slide is pulled to

the rear, lift it up and off the barrel and re- 
ceiver group assembly as shown in Figures. 

2,2 Disassembly of the Slide. 

2.2.1 Firing Pin Assembly* With the weapon 
fully assembled, the firing pin assembly (Parts 
10-I5 r Figure 3) is removed from the slid© 
{Pari 1, Figure 3) by holding the pistol with 
either hand placing the thumb of the opposite 
hand on the firing pin retainer (Part 15, Figure 
3) at the rear of the slide (Figure 7). 
Slightly squeeze the cocking grip while simul- 
taneously depressing and rotating the firing 
pin retainer clockwise forty-five degrees. The 
cocking grip is squeezed, and the firing pin 
assembly slides out of its recess without 
force. All parts of the firing pin assembly are 
removed from the slide as a single unit, Fur- 
ther disassembly of this unit seldom is re- 
quired for normal maintenance as the firing 
pin (Part 14, Figure 3) Is made of high quality 
steel that seldom if ever breaks, All parts of 
the firing pin assembly also can be cleaned 
thoroughly without further disassembly, (f re- 
placement of a firing pin assembly part is re- 
quired, however, further disassembly is ac- 



complished by removing the firing pin retainer 
(Part 15, Figure 3) and drifting the ring pin 
(Part 11, Figure 3) out of the firing pin (Part 14, 
Figure 3). Note: the firing pin is subject to 
pressure of Its main spring {Part 13, Figure 3). 
Remove the ring (Part 10, Figure 3}, the firing 
pin rebound spring (Part 12, Figure 3), and the 
main spring. Do not pull, bend, twist, or other- 
wise destroy the spring's tension.

using a screw driver. Press this tool against 
the cropped shank at the bottom of the firing 
pin block spring, unhinge it, and move the 
spring aside (Figure 8). Both the firing pin 
block and firing pin block spring come out of 
the slide upon release of the pressure of the 
firing pin block spring. 

2.2.3 Removal of Sights. Both front (Part 2 7 
Figure 3) and rear (Part & Figure 3) sights are

31, Figure 3) or screw (Part 9, Figure 3) and 
drifting the sights from their respective 
recesses. In the case of the front sight, its pin 
is drifted out from the top. 

2^,4 Extractor* Extractor Detent and Extrac- 
tor Spring. The extractor (Part 5 ? Figure 3), ex- 
tractor detent (Part 6. Figure 3), and extractor 
spring {Part 7, Figure 3) are removed from the 
slide with the aid of two punches as shown in 
Figures 8 and 9. A punch is inserted into the 
extractor groove of the slide as shown in 
Figure 9. Pressure is then applied to push the 
extractor detent to the rear. As pressure Is ap- 
plied, a small punch is Inserted into the hole 
on the bottom of the slide (Figure 9) to drift 
the extractor out through the cartridge case 
ejection slot. Following the removal of the ex- 
tractor, the extractor detent and extractor 
spring are removed by lightly tapping them 
out of the slide. 

2.2,5 Piston. The piston (Part 20 ? Figure 3) 
may be thoroughly cleaned while it remains 
attached to the slide. Where its removal is re- 
quired, however, this operation may be ac- 



complished by using a drift punch to remove 
the piston locking pin {Part 16, Figure 3), bolt 
compression (Part 17, Figure 3), piston locking 
spring (Part 18. Figure 3) and piston retaining 
pin (Part 19, Figure 3). 

2.3 Disassembly of the Barrel and Receiver 
Group, Following disassembly of the slide 
assembly group, the barrel and receiver group 
Is disassembled as follows: 

2.3.1 Recoil Spring. Lift the recoil spring {Part 
35, Figure 3) off of the barrel. 

2.3.2 Stocks. First, remove the magazine. 
Both the left (Part 48, Figure 3) and right (Part 
49, Figure 3) stocks are removed by unscrew- 
ing the stock screws (Part 34, Figure 3) and 
pushing the stocks toward the muzzle end of 
the barrel while lifting them off of the receiver, 
In removing the stock screws, care must be 
exercised to secure the stock screw retainer 
(Part 58, Figures), 

2.3.3 Sear Lever Spring. The sear lever spring 
(Part 28, Figure 3) Is disengaged from the 
knobs on the cocking lever (Part 39, Figure 3)

Figure 9, Removal of H&K Pistol P7M13 extractor. 





and the sear lever (Part 27, Figure 3) with a 
punch or screw driver. The spring then is re- 
moved genlly by manipulating it through the 
hole on the side knob of the cocking lever- 
Care must be exercised not to destroy the 
spring's tension, 

2.3-4 Cocking Lever and Grip Pin. The cocking 
lever and grip pin (Part 40, Figure 3) is re- 
moved out of the hole In the cocking grip (Part 
38, Figure 3} and cocking lever (Part 39, Figure 
3) with a punch. While removing the lever and 
grip pin, maintain pressure on the cocking 
grip with either hand. 

2,3-5 Cocking Grip and Cocking Lever* Follow- 
ing removal of the lever and grip pin, release 
pressure on the cocking grip and remove the 
cocking grip (Part 38, Figure 3) and cocking 
lever (Part 39, Figure 3) with the fingers. 

2^.6 Sear Lever. Lift the sear lever (Part 27, 
Figure 3) out of the receiver, 

2.3.7 Trigger and Grip Pin, Trigger, Trigger 
Bar, Trigger Return Spring and Disconnector, 

Removal of the trigger and grip pin (Part 23, 



Figure 3) is accomplished with a punch by 
removing the trigger and grip pin while 
holding the trigger in place with a thumb. 
After the pin is removed, the trigger (Part 22, 
Figure 3) f trigger bar (Part 24, Figure 3). trigger 
return spring (Part 21, Figure 3), and discon-

plished in the reverse order of its disas- 
sembly, The magazine follower insert is 
pressed back onto the magazine follower with 
the finger. The tongues on the magazine 
follower with its insert are aligned with the 
grooves in the magazine housing, and the en- 

; i i-;.i!y is dropped '"50 in:': hous fig 

which is held upside down. Following this, the 
magazine spring is inserted. The slot on the 
magazine locking plate is inserted into the 
magazine follower spring, and the spring is 
depressed. Depress the magazine follower 
spring by pushing down on the magazine lock- 
ing plate with a thumb. The spring, however, 
should not be compressed any further below 
the lips of the magazine housing than is re- 
quired to slide on the magazine floor plate- 
Fully seat the button on the bottom of the 
magazine locking plate into the floor plate to 
complete magazine assembly, 

3.2 Barrel and Receiver Group. The barrel and 
receiver group is assembled as follows: 

3.2.7 Trigger Guard Cover- The trigger guard 
cover catch is aligned with its hole in the 
receiver housing frame and snapped into posi- 
tion with slight finger pressure. 

3L2.2 Disassembly Button, Disassembly But- 
ton Spring, and Disassembly Button/Front 
Sight Ptor Put the disassembly button spring 
into its position in the receiver housing, insert 
the disassembly button into its recess, and in- 
sert the disassembly button/front sight pin, 

3&3 Cocking Lever Stop Pins and Cocking 
Lever Spring. The cocking lever spring is 
placed in its proper position in the receiver 
frame, aligned with the hole in the frame, and 
the first cocking lever stop pin is inserted. 
This is followed by the insertion of the second 
cocking lever stop pin. !f the first cocking 
lever stop pin also has been removed, it is 
reinserted into its hole in the receiver frame, 

3.2,4 Cocking Latch, Cocking Latch Spring, 
Cocking Lever Stop, Rocker, Magazine Catch, 
Magazine Catch Spring and Locking Pin. The 

cocking latch, cocking latch spring,, cocking 
lever stop, rocker, magazine catch, magazine 
catch spring are placed into their proper posi- 
tions in relationship to the receiver and 
aligned using a punch or assembly pin to hold 



the parts in place. The locking pin then is in- 
serted. This Is done by laying the pistol with 
its muzzle pointed to the operator's left; in- 
serting the cocking latch spring into the hote 
of the cocking latch, and then placing these 
parts into their hole in the receiver frame. 
After completion of this step, hold the parts In 
place so that the hole in the rear of the cock- 
ing latch is aligned with the hole in the re- 
ceiver. The cocking lever stop then is placed 
on top of the cocking latch, making sure that 
the bottom of the cocking lever slop Is riding 
on the second cocking lever stop pin previ- 
ously assembled and that the top hole in the 
cocking lever stop is aligned with the hole of 
the cocking latch. At this point, ensure that 
the cocking latch spring has not moved. This 
may be done by pushing up and down on the 
cocking latch to ensure resistance. Place the 
magazine catch and the magazine catch 
spring in alignment with the locking pin hole 
in the receiver frame. Lay the rocker In Its 
proper position on the receiver with its tri- 
angular knobs facing up and down and its 
point facing forward. Align the rocker hole 
with the locking pin hole in the receiver frame 
and insert the locking pin. Tap the locking pin 
into place, making sure that it is firmly seated 
in its hole to retain the rocker. Prior to pro- 
ceeding further, check to ensure that the 
cocking latch r cocking latch spring, magazine 
catch, and magazine catch spring are func- 
tioning properly and the cocking lever stop is 
firmly secured. 

32.5 Locking Pin, Slide Stop, and Slide 
Release Spring, The slide release spring and 
slide stop are placed in proper relationship to 
one another as shown in Figure 3, The locking 
pin then is inserted to retain these parts. This 
is done by first placing the hole in the slide 
stop spring in alignment with the locking pin 
hole in the receiver's frame and partially in- 
serting the locking pin. The long crooked arm 
of the spring is placed In front of the rocker, 
and the hole at the point of the slide stop is 
placed on the slide stop/disconnector pin. The 
catch near the interior angle of the slide stop 
secures the straight arm of the spring. Hold- 
ing these parts in position, the long crooked 
arm of the slide release spring is moved with 
a punch to its position on the rear side of 
the rocker. The locking pin is now inserted 
fully.

3,2.7 Trigger Bar, Trigger, Trigger Return 
Spring, and Trigger and Grip Pin. Attach the 
trigger bar to its knob on the trigger and 
emptace the trigger and trigger return spring 
in proper relationship to one another. When 
this has been done P place the trigger and grip 
pin in the hole of the trigger only sufficiently 
enough to retain the spring which must be 
engaged over the top of the trigger, slide the 
entire assembly onto the frame and into its 
proper position, and seat the trigger and grip 
pJn fufly into its hole in the receiver. When 
this assembly Is completed, check to ensure 
that the trigger spring returns the trigger by 
being properly engaged with the inner knob of 
the trigger bar. 

3£JB Sear Lever. Emplace the sear lever, en- 
suring that the sear rides on top of the 
recerver's frame, 

3££ Cocking Lever, Cocking Grip, and Cock* 
ing Lever and Grip Pin. Place the long arm of 
the cocking lever spring against the upper 
rear surface of the cocking lever, Compress 
the cocking lever and its spring so that the 
•>::!. m:; over help i:- uver the rounded knob 
cr the side of V'e sear levar with ts tip riding 
in the same slot as the sear while the cocking 
lever is engaged under the cocking latch. 
When the long arm of the cocking lever spring 
is almost fully compressed, place the upper 
tip of the cocking grip into its recess on top 
of the cocking lever with an upward motion 
that compresses the short arm of the cocking 
lever spring. After making these alignments, 
compress the entire assembfy, align I he cock- 
ing lever spring pin holes and Insert the cock- 
ing lever and grip pin with the aid of a punch. 
Following this assembfy, check to ensure that 
he cocking gi p mil depress by squeezing it 
If it will not depress f the cocking lever has 
slipped in front of the cocking latch. This can 
be prevented, by ensuring that both the cock- 
ing lever and cocking grip are depressed dur- 
ing assembfy operations, 

3.2.10 Sear Lerer Spring, Thread the sear 
lever spring through the hole on the raised 
knob on the lop side of the cocking lever. 
With a punch engage the spring's arm around 
the raised notches on the top of the cocking 
and sear levers. 

12.11 Stocks, SJide the lips on the rear of the 

stocks under the forward projections of the 
receiver frame and snap them into position 
with the thumbs; emplace the stock screws 
with their lock retainers and tighten.

over the barrel. 

3.3 Assembly of the Slide. 

3.3.1 Piston, If removed, the piston locking 
spring, bolt compression, and piston retaining 
pin are replaced In the piston. The piston is 
attached to the slide by drifting the piston 
locking pin into its position noting that it does 
not protrude from either side. 

3.3*2 Extractor, Extractor Detent and Extractor 
Spring. Place the extractor spring in its hole In 
the rear of the extractor slot followed by the 
extractor detent. The small end of the extrac- 
tor detent is toward the spring. Place the ex- 
tractor in the slot and press down and to the 
rear until it snaps into position. 

3.3.3 Front and Rear Sights. The front and 

rear sights are replaced by drifting the sights 
into their respective recesses. Once aligned, 
the pin is drifted into the front sight and the 
screw is inserted and tightened in the rear 
sight. 

3*3.4 Firing Pin Biock and Firing Pin Block 
Spring. To replace the firing pin block and fir- 
ing pin bfock spring, the spring Is mounted as 
shown In Figure 11. The shanks of the spring 
are compressed between the thumb and fore- 
finger, and the spring is placed over the 
rounded knob that is an Integral part of the IV- 
ing pin block. The firing pin block and spring 
are inserted into their position in the slide. 
Depress the cropped shank of the firing pin 
block spring and press it under its locking 
flange, 

3,3.5 Firing Pin Assembly. Assemble the firing 
pin rebound spring, main spring ring, and in- 
sert the ring pin. Align the slot in the firing pin 
retainer with the firing pin pawl and slide onto 
the firing pin. Depress the firing pin retainer 
until it can be rotated to seat the firing pin 
pawl. Align the firing pin assembly with its 
recess in the slide and push into place. Place 
I he thumb on the firing pin retainer and rotate 
counterclockwise until the assembly snaps in- 
to position.

4. Functioning 



4.1 Steps. There are four (4) distinct steps In 
the functioning of the H&K Pistol P7M13. They 
are as follows. 

4.7.1 First Step— Weapon Loaded and Un- 
cocked, When the H&K Pistol P7M13 is loaded 
with a magazine and a round is seated In its 
chamber, the weapon is in the first step of its 
functioning. Its various parts are In the posi- 
tions depicted in Figures 12 and 13, The 
pistol's slide is closed with the face touching 
the base of the cartridge seated in the 



weapon's chamber, but the pistol still is fully 
safe. This is due to the firing pin rebound 
spring (12) holding the firing pin (14) in the rest 
position while the cocking lever spring (47) 
also holds the cocking lever (39) in its forward 
position. Until deliberate pressure Is applied 
against the cocking grip (38) by the operator, 
the cocking lever will not allow the sear lever 
(27), under pressure of the sear lever spring 
(28), lo pivot down and disengage the sear. 
The sear lever therefore remains In contact 
with the receiver and positioned in front of the 
firing pin cocking pawl, preventing discharge 
o< the weapon as the firing pin cannot engage 
the cap of the cartridge seated In the 
weapon's chamber. The firing pin block (3) 
also provides a further positive safety. All 
safety features are retained until pressure Is 
applied to the trigger. 

4.1,2 Second Step— Weapon Loaded and 
Cocked Deliberate hand pressure on the 
cocking grip (38) causes the H&K Pistol 
P7M13 to cock. When this is done, the pistol 
is in its second step of functioning as 
depicted in Figure 14. In this step of the 



18 



Figure 12. First step of functioning, H&K Pistol P7M13 (right side view}. 



3 27 28 




weapon's functioning, (he cocking lever (39) is 
pressed back by the cocking grip (38). The 
cocking latch (45) then engages and holds the 
cocking Fever in place as the sear lever {27) Is 
in front of the release edge of the trigger bar 
(24), When the sear lever moves back, it over- 
comes the tension of the firing pin spring (13) 
and prepares the weapon for aiming and 
firing, 

4*1,3 Third Step— Weapon Fired, Rearward 
finger pressure against the trigger {22) pivots 
the sear lever {27) clear of the pawl on the fir- 
ing pm {14), This pivoting movement of the 
sear lever also pufls down the firing pin block 
(3), to allow the firing pin to move foreward 
under the pressure of the firing pin spring (13) 
The tip of the firing pin hits the primer In the 
base of the cartridge seated in the weapon's 
chamber, and the piece is fired. Positions of 
the pistol's component parts after firing are 
shown in Figure 15. Recoil has overcome the 
pressure of the recoil spring (Part 35, Figure 
3), and the slide has moved to the rear. In this 
moment, the empty cartridge case is ex- 
tracted from the chamber and ejected from 



the weapon by the forward edge of the tip of 
the slide stop. When recoil is expended, the 
tension of the recoil spring moves the slide to 
the front. As it moves forward, the face of the 
bolt picks up a new round forced upward by 
pressure of the magazine follower spring on 
the follower, and the new round is seated in 
the chamber as the slide fully closes. 

4.1.4 Fourth Step— Weapon After Firing Lest 
Round. When the last round In a magazine 
loaded Into the H&K Pistol P7M13 has been 
fired, the magazine follower (53). pushed up- 
ward by the magazine follower spring (55), 
reacts against the slide stop {26) to hold the 
slide (1) to the rear as shown In Figure 16. To 
return the pistol to an unloaded and uncocked 
position, pressure is applied to the cocking 
grip (38). As the cocking grip moves to the 
rear, the rocker (41) is rotated by the nose on 
the cocking lever (39), This pivots the slide 
stop down out of the position to hold back the 
slide. The slide then moves forward under 
pressure of the tensioned recoil spring (Part 
35 f Figure 3), and the firing pin (14) again is 
cocked by the sear lever.

5. Trouble Shooting 



5.1 General, In the ©vent of a malfunction, the 
pistol must be treated as if it is loaded until it 
has been cleared. 

5.2 Immediate Aetton. Most malfunctions will 
be eliminated by the application of immediate 
action procedures designed to overcome stop- 
pages. These stoppages and appropriate cor- 
responding immediate actions for eliminating 
them are: 

5.2.1 Failure to Feed. A failure to feed a new 
cartridge into the pistol's chamber most often 
stems from the maga2ine not being fully 
seated. Immediate action to remedy this condi- 
tion consists of tapping the bottom of the 
magazine with the palm of the non-shooting 
h/im::, ■:■;■:•:::.! y the piece, p eairring *he pistol, 
and retiring the weapon, 

5.2-2 Failure to Eject A failure to eject a fired 
cartridge case may stem from a short recoil 
stroke of the slide, Immediate action to 
remedy this condition consists of pulling the 
slide fully to the rear, releasing It, and seating 
a new round in the weapon's chamber, 

5,2.3 Failure to Extract Complete failures to 
extract on the H&K P7M13 results only from a 
broken extractor, but a ruptured cartridge may 
cause the new next round to be fed only par- 
tially into the chamber. In the event that a 
round fails to be seated in the chamber, look 
to see If this has happened. When this occurs, 
push the magazine catch and release the 
magazine from its housing; pull the slide and 
remove the ruptured cartridge by pulling the 
slide fully to the rear several times or using a 
ruptured cartridge case extractor.

sible for the care, cleaning, and condition of 
the H&K Pistol P7M13 at all times. Defects 
and malfunctions are reported to the unit's 
armorer, or commercial weapons are returned 



25 



to HK Inc. for rnainienarvce. In military units, 
the armorer is responsible for replacement or 
repair of defective parts, maintaining and ac- 
counting for replacement parts in accordance 
with prescribed supply procedures, and for- 
warding unit weapons to his direct support 
unit for any required maintenance beyond his 
capabilities- In the event of breakage, Beta 
lights {Part 61, Figure 3} on sights (items 
available only on H&K P7M13 commercial 
models) will be replaced by HK, Inc. under 
terms of the pistol's warranty or at nominal 
cost. 

6*2 Tools and Materials- Commercial tools 
and materials for the care and cleaning of the 
H&K Pistol P7M13 are shown in Figure 17- 
U.S. Government issue cleaning materials 
equally are acceptable for the maintenance of 
this pistol- However, no metallic objects; syn- 
thetic materials, e.g., nylon or Perlon cloth 
(when the weapon is hot from firing); chemical 
solvents, e.g-, petroleum ether; or cold or hot 
water should be used on this weapon. In addi- 
tion to materials depicted in the kit at Figure 
17, the following materials also may be used 
in tfte care and cleaning of th H&K Pistol 
P7M13. 

6.2.1 Cleaning Rags. Except as noted for syn* 
thatic materials above, cleaning rags may be

6,3 Ordinary Cleaning and Lubrication. The 

H&K Pistol P7M13 is cleaned following each 
use by the user (firer). For this purpose, the 
pistol is disassembled as far as it is neces- 
sary to clean all fouled parts. Disassembly, 
however, normally is not required beyond the 
three main groups of the weapon. The extent 
of the weapon's disassembly nevertheless will 
depend on the number of rounds fired and the 
compound of the propellant in the ammunition 
used during firing. In routine cleaning opera- 
tions, the various parts of the pistol are 



treated as follows: 

6.3.7 Slide, The slide of the pistol is cleaned 
with a brush or cloth and then lightly lubri- 
cated with oil. 

6,3.2 Rece/ver and Barrel The barrel is 

cleaned by pulling a brush, patches, or wicks 
through it with the pull-through HK chain or a

brushes, patches, or wicks are pulled clean 
through from the weapon's chamber to lis 
muzzle- initial bore cleaning should be done 
as soon after firing as possible while the bar- 
rel is still warm to the touch. Cleaning with 
brushes, patches, or wicks continues until no 
dirt is shown on a patch or wick. Other parts 
of the barrel and receiver group are cleaned 
with brushes and cloths. Both the inside and 
outside of the barrel Is then lightly oiled- 
Cleaning of the bore is repeated on each of 
three days after 



6.3*3 Magazine. Following normal use r dirt 
and impurities are removed from magazine 
lips and the follower with brushes and cloth. If 
the magazine has been subjected to sand and 
other dirt. It is disassembled and thoroughly 
cleaned. Following all cleaning operations, the 
magazine and all its parts are lightly 
lubricated. 

6.4 Thorough Cleaning. While the degree of 
fouling of Ihe H&K Pistol P7M13 and the ex- 
tern of its normal cleaning depends on the 
number of rounds fired In the weapon and the 
compound of the propellant in used ammuni- 
tion, a thorough cleaning of the weapon is re- 
quired at regular intervals of not less than one 
year and/or after firing 1,000 rounds. Such 
cleaning operations are conducted on the 
various major assemblies of the H&K Pistol 
p7M13as follows: 

6-4. f Slide. Rinse the slide of the H&K Pistol 
P7M13 in petroleum and clean it thoroughly 
with a brush and cloths to remove all dirt and 
Impurities; wipe the slide with a dry cloth, and 
lightly lubricate it. Never use hard objects to 
clean the slide as they may destroy its finish. 
The firing pin block spring normally is not 
removed from the firing pin block as its spring 
could be damaged or distorted. When the fir- 
ing pin block and its spring are being cleaned 
with a brush, care should be exercised to pre- 
vent bristles from becoming stuck to the firing 
pin block as they may cause these parts to 
stick during firing. It is not necessary to dis- 
assemble the piston assembly to clean it. The

piston may be thoroughly cleaned with a cloth 
and lightly lubricated. Never use sharp edges 
to clean the front section of the piston as 
they may damage it Powder residue between 
piston rings should be allowed to remain as it 
does not affect operation of the weapon since 
the piston is seff-cfeaning during firing, Firing 
prn assemblies, however, are disassembled 
during thorough cleaning operations. For this 
disassembly, the thumb is used to rotate the 



firing prn retainer and detach the firing pin 
assembly from the slide. The firing pin as- 
sembly is washed In petroieum, dried, lighlly 
lubricated, and reassembled, 

&42 Barrel and Receiver. The piston cylinder 
fS cleaned In a similar manner to the barrel 
using a brass brush- The brush is screwed up 
and down the inside walFs of the cylinder prior 
to being soaked. After brushing, tap the 



27 



receiver barrel end down several times on a 
flat surface to remove the carbon from Inside 
the cylinder. Other moving pans of the 
receiver group are soaked in petroleum, dried, 
and lightly oiled, the barrel also is cleaned 
with brushes, patches, and/or wicks soaked <n 
oil, During barrel cleaning, the flutes of the 
chamber are cleaned with a brass brush and 
oil. After the barrel and chamber have been 
cleaned, oiled wicks or patches are pulled 
through the barrel from the chamber to its 
muzzle to lightly lubricate the bore. Outside 
surfaces of the barrel also are lightly 
lubricated. Following initial cleaning, the bar- 
rel and chamber are cleaned for the next three 
days after firing by pulling a brush, wicks, or 
patches from the chamber to the muzzle until 
they show no dirt. The bore and chamber are 
lightly oiled after each cleaning operation, 

6AJ3 Magazine. The magazine should be 
disassembled with care as bending of the 
magazine follower spring (Part 55, Figure $ 
could cause failure to feed— problems by 
varying the tension of that spring. Its com- 
ponent parts are washed in petroleum; all dirt 
is removed, especially from the interior of The 
magazines lips; the parts are dried; lightly 
lubricated; and reassembled. 



7. Inspections 



7.1 When. Inspections are conducted after all 
thorough cleaning operations or repairs. 

7.2 How. Upon completion of weapon 
assembly, the H&K Pistol P7M13 is inspected 
in the following steps: 

7.2.1 First Step- The slide is pulled to the rear, 
snapped forward, and the trigger is pulled to 
check the overall functioning of the weapon. 

7.2.2 Second Step. The magazine catch Is dis- 
engaged, and the magazine is allowed to fall 
free of the receiver. It is checked visually to 
ensure that it is in serviceable condition and 
that its lips are not bent. The magazine lock- 
ing plate is checked to ensure that it is fully 
engaged. The magazine then is loaded to its 
full capacity with thirteen (13) dummy rounds, 



checked to ensure that a free space remains 
in the magazine below the last dummy car- 
tridge, and inserted into the receiver to ensure 
that loading and insertion operations take 
place in a trouble tree manner with the 
magazine being fully retained by its catcti. 

7.2.3 Third Step* Pull the slide all the way 

back several times, letting It snap forward 
each time to ensure that dummy cartridges 
are fed into the chamber, extracted, and 
ejected in a trouble free manner. To determine 
whether or not I he slide is retained In Its rear 
position, these operations are repeated until 
the last dummy round has been loaded into 
the chamber, extracted therefrom, and 
ejected. 

7.2.4 Fourth Step. Press the cocking grip to 
ensure that the slide snaps forward freely into 
its most forward position. 

7.2.5 Fifth Step, Use gauges 9224 L2-L5 
(Figure 18) as follows: 

7*2.5.1 First Gauging Operation. Use 

gauge 9224 L-2 lo check the functioning of 
the disconnector. This is done by inserting 
the gauge Into the barrel with Its clamping 
lever released. Depress the pistol onto the 
gauge until the muzzle touches its space 
plate. While keeping the pistol depressed 
on the gauge, tighten the damping lever of 
the gauge and remove the gauge's space 
plate. This retains the slide in a slightly 
unlocked position where a properly func- 
tioning disconnector will have pressed the 
trigger bar out of the way of the sear lever 
to prohibit firing pin movement— a positive 
safety feature. If a gauge is not available, 
this operation also may be conducted by 
placing the slide on the edge of a work 
bench or table and pushing slightly down 
on the slide to achieve the same effect as 
with a gauge. Squeeze the cocking grip 
and pull the trigger. If the firing pin snaps 
forward, the disconnector is broken or it 
has been assembled Improperly. 

7.Z5-2 Second Gauging Operation. Inspec- 
tion of the safety and the firing pin front 
and rear protrusions are made with gauge 
9224 L3 in the following manner 

7,2-5-2. 1 Step One, Unscrew the right grip 
from the receiver. 

7.2*5*2*2 Step Two. Pull the slide to the 
rear with one hand while depressing the

engage the slide and remove the right grip- 

7.2.5-2-3 Step Three. Take up the normal 
slack distance of the trigger. With the trig- 
ger slack held, place the pistol so that its 
muzzle is pointed in the air. With the 
weapon end its parts still remaining in 
thQse positions, place the firing pin re- 
tainer on the 9224 L3 inspecting gauge 



and press down on the pistol until the 
firing pin retainer can be depressed no 
further (Figure 19). 

7,2,5.2.4 Step Four, With the pistol con- 
tinuing to be held in the position described 
In Step Three, insert the depth gauge por- 
tion of gauge 9224 L3 into the barrel and 
push it down as far as it will go without 
the application of force. The centrally 



29 



located movable measuring peg of the 
gauge must be even with the lower surface 
of the end of the depth gauge (Figure 20). 
II this Is not the case, the ring may be 
defective, allowing the firing pin to pro- 
trude too far. 

7,2,5,2.5 Step Five, Apply pressure to the 
cocking grip with the right thumb and 
against the trigger with the left thumb, 
This releases the firing pin to move to its 
forward position. Push down on the depth 
gauge without the application of undue 
force. The centrally located movable 
measuring peg of the depth gauge must 
be positioned between the upper and 
lower measuring levels of the gauge. If this 
is not the case, inspect the firing pin 
spring for serviceability. If it is serviceable, 
the firing pin most likely is worn. Replace 
It or the firing pin spring as appHcaWe. 

7.2.5.3 Third Gauging Operations. Gauge 
9224 L4 is used to measure trigger pull. Its 
upper arm is placed over The trigger while 
the muzzle of the pistol is pointed in the 
air. The cocking grip Is depressed, and 
weights then are added to the gauge until 
sufficient weight has been applied to the 
trigger to release the weapon's firing pin. If 
more than 2,9 kilograms of weight are re- 
quired to release Ihe firing pin, the firing 
pin sear lever may be burred or bent If 
less than 1,8 kilograms of weight are re- 
quired, replace the trigger spring. 

7.2.5.4 Fourth Gauging Operation- Gauge 
9224 L5 is used to determine the caliber of 
the barrel. If the bore is not within Govern- 
ment prescribed limits for 9mm weapons, 
the barrel of the pistol must be replaced. 



formed ir\ a trouble free manner with the 
magazine being fully retained by its catch. 

ftl.2 Step Two. Pull the slide of the H&K 
Pistol P7M13 all the way back several times, 
letting it snap forward each time- This is done 
to ensure that dummy cartridges are fed into 
the chamber, extracted, and ejecied in a 
trouble free manner. These operations are re- 
peated until the last dummy round has been 
loaded into the chamber, extracted, and 
ejected to determine whether or not the slide 
is retained in its rear position. 

& 1-3 Step Three. Disengage the magazine 
catch of the H&K Pistol P7M13 to ensure that 
the magazine drops freely out of the receiver, 

8.1.4 Step Four, Press the grip to ensure that 
the slide snaps forward freely into its most 
forward position. 

&15 step Five. Press In the disassembly but- 
ton and pull back the slide all the way, 
detaching It from the receiver. Reattach the 
slide and continue. 

8.1.6 Step Six. Pull back the cocking grip and 
look to see if the firing pin protrudes beyond 
the rear of the slide. Slightly loosen the cock- 
ing grip about 3-4mm and ensure that the 
cocking latch engages the cocking lever by 
seeing that the firing pin still protrudes to the 
rear of the slide. 

8.1.7 Step Sewn. Release the cocking grip all 
the way and look to see that the firing pin has 
disappeared into its slide recess. 

8.1.8 Step Eight Squeeze the cocking grip 
and pull the trigger to ensure thai the firing 
pin snaps forward. 



8. Operational Testing 



9. Barrel Replacement 



8.1 Steps. Operational testing of the H&K 
Pistol P7M13 is conducted as follows: 

8.1,1 Step One. Load the magazine to its full 
capacity with thirteen (13) dummy rounds, in- 
sert it into the receiver, and ensure that 
loading and insertion operations are per- 



Barrels of H&K Pistols P7M13 may be re- 
placed by direct support maintenance units, 
or by HK, Inc. In the case of commercial 
models. To disassemble the barrel from the 
receiver, the slide stop/disconnector pin (Part 
59, Figure 3} is drifted out and the barrel Is

removed by driving out the barrel with another 
old salvaged barrel and a hammer. To place a 
new barrel on the receiver, align the notch in 
the barrel with the extractor notch in the 
receiver, place the pistol in a vise with its 
parts protected by cloth (Figure 21), press the 
barrel into place so that the slid© stop/discon- 
nector pin hole in both the barrel and receiver 
are aligned, artd insert the slide stop/dis- 



connector pin. In lieu of a vice- a block of 
wood and a hammer may be used to drive the 
barrel into place so that the slide stop/discon- 
nector pin hole in both the barrel and receiver 
are aligned. The insertion of the slide stop/ 
disconnector pin automatically sets the re- 
quired headspace for the barrel as well as 
aligning the extractor with the slide.
